Android app which detects snoring or sleep anomalies by recording audio (it doesn't need to analyze it itself). I tried the
haven app, but it doesn't work on Android 13.
Sleep as Android by Petr Nálevka claims to detect snoring (which is associated with obstructive sleep apnea).
I have personally used Sleep as Android, and it is quite good. I have not, however, used the specific feature to detect snoring. If I recall correctly, it is so advanced that you can sync it with another device to filter out snoring from a bed partner.
The official website is:
The link to the app on Google's Play store is:
The link to the paid unlocker on Google's Play store is:
The paid unlocker unlocks additional features. I don't know if the paid unlocker is needed for the snore detection feature.
One of the many things I like about Sleep as Android is that the developer(s) is/are constantly improving it. Updates are frequent (once or twice per month) and add new functionality plus fix known bugs.
I have personally recommended Sleep as Android to quite a few people, and I've never heard a complaint. Everyone seems to like it.
